Agree, 100%. Beards need to be neat and trimmed!!! Short of Santa, no one looks good with a shaggy unkempt beard. You want to look like a caveman or crazy recluse or ignorant hick or Islamic terrorist, go for the untrimmed, long beard. Otherwise, be civilized and smart with a trimmed beard. Yes, I've had beards for 40+ years.
This woman agrees with you.
1-2 cm. here.
I’ve only had the goatee for a few years, but I agree. It needs to have a nice sharp edge to it. And even when I tried full facial I still created a neck line and trimmed to that line. I actually thought about trimming the top on the cheek but never got that into it. It became a goatee pretty quick because that is the only part of my face that produces a thick enough beard.
